  1. High DPC in windows 10 home 64 bit 1909


    I have high latency dpc in my pc hardware, my hardware and bios are uptodate, kindly see the dpc result as below:


    IComputer name: DESKTOP-UI7B4KE
    OS version: Windows 10 , 10.0, build: 18363 x64
    Hardware: MS-7917, MSI, Z97A GAMING 6 MS-7917
    CPU: GenuineIntel IntelR CoreTM i7-4790K CPU @ 4.00GHz
    Logical processors: 8
    Processor groups: 1
    RAM: 8140 MB total


    _________________________________________________________________________________________________________
    CPU SPEED
    _________________________________________________________________________________________________________
    Reported CPU speed: 40 MHz

    Note: reported execution times may be calculated based on a fixed reported CPU speed. Disable variable speed settings like Intel Speed Step and AMD Cool N Quiet in the BIOS setup for more accurate results.

    WARNING: the CPU speed that was measured is only a fraction of the CPU speed reported. Your CPUs may be throttled back due to variable speed settings and thermal issues. It is suggested that you run a utility which reports your actual CPU frequency and temperature.


    _________________________________________________________________________________________________________
    MEASURED INTERRUPT TO USER PROCESS LATENCIES
    _________________________________________________________________________________________________________
    The interrupt to process latency reflects the measured interval that a usermode process needed to respond to a hardware request from the moment the interrupt service routine started execution. This includes the scheduling and execution of a DPC routine, the signaling of an event and the waking up of a usermode thread from an idle wait state in response to that event.

    Highest measured interrupt to process latency µs: 84.40
    Average measured interrupt to process latency µs: 3.039606

    Highest measured interrupt to DPC latency µs: 64.80
    Average measured interrupt to DPC latency µs: 0.951912


    _________________________________________________________________________________________________________
    REPORTED ISRs
    _________________________________________________________________________________________________________
    Interrupt service routines are routines installed by the OS and device drivers that execute in response to a hardware interrupt signal.

    Highest ISR routine execution time µs: 120.20950
    Driver with highest ISR routine execution time: dxgkrnl.sys - DirectX Graphics Kernel, Microsoft Corporation

    Highest reported total ISR routine time %: 0.032341
    Driver with highest ISR total time: dxgkrnl.sys - DirectX Graphics Kernel, Microsoft Corporation

    Total time spent in ISRs % 0.052211

    ISR count execution time <250 µs: 14342
    ISR count execution time 250-500 µs: 0
    ISR count execution time 500-999 µs: 0
    ISR count execution time 1000-1999 µs: 0
    ISR count execution time 2000-3999 µs: 0
    ISR count execution time >=4000 µs: 0


    _________________________________________________________________________________________________________
    REPORTED DPCs
    _________________________________________________________________________________________________________
    DPC routines are part of the interrupt servicing dispatch mechanism and disable the possibility for a process to utilize the CPU while it is interrupted until the DPC has finished execution.

    Highest DPC routine execution time µs: 151.814750
    Driver with highest DPC routine execution time: nvlddmkm.sys - NVIDIA Windows Kernel Mode Driver, Version 432.00 , NVIDIA Corporation

    Highest reported total DPC routine time %: 0.023975
    Driver with highest DPC total execution time: nvlddmkm.sys - NVIDIA Windows Kernel Mode Driver, Version 432.00 , NVIDIA Corporation

    Total time spent in DPCs % 0.055018

    DPC count execution time <250 µs: 25014
    DPC count execution time 250-500 µs: 0
    DPC count execution time 500-999 µs: 0
    DPC count execution time 1000-1999 µs: 0
    DPC count execution time 2000-3999 µs: 0
    DPC count execution time >=4000 µs: 0


    _________________________________________________________________________________________________________
    REPORTED HARD PAGEFAULTS
    _________________________________________________________________________________________________________
    Hard pagefaults are events that get triggered by making use of virtual memory that is not resident in RAM but backed by a memory mapped file on disk. The process of resolving the hard pagefault requires reading in the memory from disk while the process is interrupted and blocked from execution.

    NOTE: some processes were hit by hard pagefaults. If these were programs producing audio, they are likely to interrupt the audio stream resulting in dropouts, clicks and pops. Check the Processes tab to see which programs were hit.

    Process with highest pagefault count: searchindexer.exe

    Total number of hard pagefaults 3
    Hard pagefault count of hardest hit process: 1
    Number of processes hit: 3
